INTRODUCTION: The present study aimed (a) to evaluate the clinical and radiographic characteristics of hand erosive osteoarthritis (EOA) in a group of consecutive patients, (b) to correlate the severity of radiographic involvement with clinical and laboratory findings and (c) to associate the levels of pain and functional impairment with some radiographic findings. METHODS: Patients with EOA were consecutively enrolled. Inclusion criteria required the American College of Rheumatology (ACR) criteria for hand osteoarthritis and the presence of at least one joint in "E" or "R" phase according to Verbruggen-Veys. For each patient, demographic and clinical data were collected including evaluation of pain and function with the Australian Canadian Osteoarthritis Hand Index (AUSCAN) scale and Health Assessment Questionnaire (HAQ). Laboratory parameters and plain radiography of both hands were also collected. Each radiograph was evaluated in accordance with the Verbruggen-Veys classification and scored with the Kallman score. RESULTS: During the study period 60 patients (M/F 13:47) with EAO were enrolled. More severe radiographic disease ("E" or "R") was often found at II and III distal interphalangeal (IP) joints. In addition, Kallman score, presence of osteophytes, erosions and joint space narrowing correlated significantly with duration of symptoms, AUSCAN, pain and active joints. More severe radiographic involvement was associated with AUSCAN and with the presence of ankylosis only at proximal IP joints. CONCLUSION: The present study showed that EOA is characterised by a significant correlation between radiographic involvement and some clinical characteristics of the disease. However, an impairment of joint function was mainly associated to radiological proximal IP joint involvement, but not with other symptoms such as pain.
